xcom-hacks

This is an ugly, nasty hack which should prevent XCOM:Enemy within (Steam/Linux) from crashing more often than UFOs. Although it looks, smells and tastes pretty hacky, it worked surprisingly well for me (not a single segfault using this hack). I finished nearly the whole "enemy within" using it and tested three consecutive "enemy unknown" missions (without the extension). Some background information about the crash: http://psydk.org/archives/2014-07-05-221-introducing-plasma-fence

Step 1 (both versions) : compile

gcc -ldl -shared -fPIC -o libxcomfix.so -std=gnu11 xcomfix.c
